PMS – Premenstrual Syndrome
A collection of physical, emotional, and behavioral symptoms that occur cyclically in the luteal phase of the menstrual cycle, starting after ovulation and typically resolving with the onset of menstruation. Symptoms of PMS can include mood swings, irritability, depression, anxiety, bloating, breast tenderness, headache, and fatigue. The etiology of PMS is thought to be related to hormonal fluctuations, particularly involving estrogen and progesterone, as well as potential neurotransmitter involvement such as serotonin. The severity of symptoms can vary widely among individuals, and in some cases, symptoms can significantly impact daily functioning.
Key Features:
- Symptoms:
- Emotional and Behavioral Symptoms: Mood swings, irritability, anxiety, depression, crying spells, social withdrawal, and changes in libido.
- Physical Symptoms: Bloating, breast tenderness, headache, fatigue, sleep disturbances, and gastrointestinal symptoms such as constipation or diarrhea.
- Cognitive Symptoms: Difficulty concentrating, forgetfulness, and confusion.
- Timing:
- Symptoms typically begin after ovulation (around day 14 of a 28-day cycle) and resolve with the onset of menstruation (day 1 of the cycle).
- The luteal phase, where symptoms occur, spans from ovulation to the start of menstruation, usually lasting about 14 days.
- Etiology:
- The exact cause of PMS is not fully understood, but it is believed to involve hormonal fluctuations, particularly in estrogen and progesterone levels.
- Neurotransmitter changes, especially involving serotonin, are also thought to play a role in the mood-related symptoms of PMS.
- Genetic, environmental, and lifestyle factors may contribute to the severity and presence of PMS symptoms.
- Diagnosis:
- Diagnosis is typically based on a pattern of symptoms that occur cyclically in relation to the menstrual cycle.
- Keeping a symptom diary for several menstrual cycles can help in diagnosing PMS and differentiating it from other conditions.
- Management and Treatment:
- Lifestyle modifications, such as regular exercise, a balanced diet, adequate sleep, and stress management, can help alleviate symptoms.
- Medications, including nonsteroidal anti-inflammatory drugs (NSAIDs), hormonal contraceptives, antidepressants (SSRIs), and diuretics, may be prescribed based on symptom severity.
- Cognitive-behavioral therapy (CBT) and other supportive therapies can also be beneficial for managing emotional and behavioral symptoms.
